Chromatin Immunoprecipitation and High-Throughput Sequencing (ChIP-Seq): Tips and Tricks Regarding the Laboratory Protocol and Initial Downstream Data Analysis.

Chromatin immunoprecipitation coupled with high-throughput sequencing (ChIP-seq) has become an essential tool for epigenetic scientists. ChIP-seq is used to map protein-DNA interactions and epigenetic marks such as histone modifications at the genome-wide level. Here we describe a complete ChIP-seq laboratory protocol (tailored toward processing tissue samples as well as cell lines) and the bioinformatic pipelines utilized for handling raw sequencing files through to peak calling.
